[0002] The basic component unit of lead-acid batteries is the pole group, which is assembled from negative plates, positive plates, and separator paper. The separator paper is used to wrap the positive plate and separate the positive plate from the negative plate. In the assembly process of the pole group, the positive plate is usually wrapped with separator paper and then stacked with the negative plate (or side negative plate) to form a group, and then the positive and negative plate groups after multiple stacking are stacked to form a pole group. In order to improve efficiency and reduce risks, the above operations are currently mostly completed automatically by equipment.

[0003] In the current operation of coating the positive plate with separator paper and stacking it with the negative plate, when the plate is loaded by standing upright on its side, the loading channel is advanced in a horizontal manner, that is, all the plates on the same loading channel are at the same height, such as the invention application with application number CN201210372465.0 and name "Fully automatic lead-acid battery plate packaging machine", the utility model patent with application number CN201620412292.4 and name "A lead-acid battery plate packaging machine", and the invention application with application number CN202110591371.1 and name "Multi-station battery plate packaging and assembly machine". In this way, support structures are required at both ends of the plate to prevent the plate from falling down, and when a support or blocking structure for the plate is provided at the end of the loading, it is inconvenient to remove the plate from the end. In order to avoid this problem, the utility model patent with application number CN201620412292.4 and titled "A Lead-acid Battery Packing Machine" adopts a block with a beveled edge on the feeding channel to support the plate, so that the plate can be tilted at an angle. However, in this structure, when the friction between the plate and the conveying channel is insufficient, the plate at the feeding end may slide and fail to form a tilted state.

DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary descriptions, and are only schematic diagrams, not actual pictures, and cannot be understood as limiting the present patent; in order to better illustrate the embodiments of the utility model, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Embodiment 1

[0034] A lead-acid battery automatic packaging machine, such as Figure 1-Figure 3 As shown, it includes a frame 7 and a feeding mechanism 1, a film taking mechanism 2, a film wrapping mechanism 3, a film stacking mechanism 4, a transfer mechanism 6 and a power mechanism 5 arranged on the frame 7, wherein the feeding mechanism 1 and the film taking mechanism 2 are each provided with three groups, the three groups of feeding mechanisms 1 are arranged in parallel at the front of the frame 7, each group of film taking mechanisms 2 is arranged at the discharge end of one group of feeding mechanisms 1, the film stacking mechanism 4 and the feeding mechanism 4 are arranged in a vertical direction, and the working area of ​​each group of film taking mechanisms 2 extends to the film stacking mechanism 4, and the transfer mechanism 6 is arranged at the discharge end of the film stacking mechanism 4. The three groups of feeding mechanisms 1 are respectively used for feeding the positive plate 82, the negative plate 81 and the edge negative plate, and the feeding mechanism 1 for the positive plate 82 is located at the outermost end of the film stacking mechanism 4, away from the transfer mechanism 6. The stacking mechanism 4 is provided with a wrapping mechanism 3 near the feeding mechanism for the positive plate 2, and the wrapping mechanism 3 spans the stacking mechanism 4. The sheet taking mechanism 2 transfers the positive plate 82 from the feeding mechanism 1 to the stacking mechanism 4. The stacking mechanism 4 transports the positive plate 82 to the wrapping mechanism 3 to wrap the separator paper, and then enters the stacking mechanism 4. In this embodiment, the wrapping mechanism 3 and the transfer mechanism 6 can adopt the existing technology, which will not be repeated here.

[0035] like Figure 2 and Fig. 9As shown, the power mechanism 5 includes a main motor 52 with multiple output ends, and the rotational motion of the main motor 52 is transmitted to the film taking mechanism 2, the film wrapping mechanism 3, the film stacking mechanism 4 and the transfer mechanism 6 through the chain 51, which greatly improves the use efficiency of the main motor 52.

[0036] like Figure 4-Figure 6 As shown, the feeding mechanism 1 includes a feeding channel 11, a first fork 12, a first motor 13, a second fork 14 and a second motor 15. The feeding channel 11 is arranged on the frame 7, and the first fork 12 is arranged above the feeding channel 11. The first motor 13 drives the first fork 12 to reciprocate along the length direction of the feeding channel 11; the second fork 14 passes through the bottom of the feeding channel 11 and exceeds the upper surface of the feeding channel 11, and the second motor 15 drives the second fork 12 to reciprocate along the length direction of the feeding channel 11.

[0037] like Figure 3 As shown, the feeding channel 11 is arranged in an inclined shape along the horizontal direction, that is, the horizontal height of the feeding channel 11 at one end away from the film taking mechanism 2 is lower than the horizontal height of the feeding channel 11 at one end close to the film taking mechanism 2, and the inclined angle A can be set to 10-30 o .

[0038] In this embodiment, Figure 6 As shown, the first fork 12 is arranged at one end of the feeding channel 11 away from the film-taking mechanism 2. Of course, its stroke can also include the entire length direction of the feeding channel 11, and its lower end is a comb-tooth structure. The second fork 14 is arranged at one end of the feeding channel 11 close to the film-taking mechanism 2. Similarly, its stroke can also include the entire length direction of the feeding channel 11, and its upper end is also a comb-tooth structure. The teeth of the second fork 14 pass upward from the bottom of the feeding channel 11 and exceed the upper surface of the feeding channel 11. Therefore, in order to ensure that the second fork 14 can reciprocate along the length direction of the feeding channel 11, the feeding channel 11 is at least close to the film-taking mechanism 2. There are multiple support bars 111 arranged along the length direction, and there is a gap between the support bars 111 and the support bars 111, and the teeth of the second fork 14 pass through the gap. When the first fork 12 and the second fork 14 reciprocate along the length direction of the feeding channel 11, the teeth of the first fork 12 and the teeth of the second fork 14 can be staggered with each other, that is, the teeth of the second fork 14 can pass through the gap between the teeth of the first fork 12, and the teeth of the first fork 12 can also pass through the gap between the teeth of the second fork 14. When the first fork 12 pushes the electrode plate 8 forward, the second fork 14 can push the electrode plate 8 from the bottom or rear of the first fork 12 without interference. Therefore, when the second fork 14 pushes the electrode plate 8 to wait for the sheet transfer, the first fork 12 can still accept the feeding of the electrode plate 8, which reduces the waiting time and greatly improves the efficiency.

[0039] Moreover, the comb teeth of the first fork 12 and the second fork 14 are perpendicular to the length direction of the feeding channel 11, and the electrode plate 8 is also transported in a manner of being placed perpendicular to the length direction of the feeding channel 11. In this way, the electrode plate 8 can be kept in a backward tilted manner at an angle to the horizontal plane, which is convenient for the operation of taking the plate later.

[0040] Of course, the upper and lower positions of the first fork 12 and the second fork 14 can be interchanged, that is, the first fork 12 can pass through the bottom of the feeding channel 11, and the second fork 14 can be located above the feeding channel 11.

[0041] like Figure 7-8 As shown, the film taking mechanism 2 includes a turntable 21, a pull rod 22, a guide rail 23, a moving block 24, a guide plate 25, a connecting seat 26, a guide rod 27, a connecting block 28 and a film taking head 29. The turntable 21, the guide rail 23 and the guide plate 25 are all arranged on the frame 7. One end of the pull rod 22 is arranged on the turntable 21 and the other end is connected to the moving block 24. The moving block 24 is arranged on the frame 7 through the guide rail 23. When the turntable 21 rotates, one end of the pull rod 22 rotates with the turntable 21, and the other end pulls the moving block 24 to perform linear motion along the guide rail 23, so that the rotational motion of the turntable is converted into the linear motion of the moving block 24. One end of the connecting seat 26 is also connected to the moving block 24, and performs linear motion with the moving block 24. The other end of the connection seat 26 is connected to the guide rod 27 and the connection block 29. The guide rod 27 passes through the connection seat 26 and the connection block 29 to connect the two into a whole. At the same time, the guide plate 25 is provided with a guide groove 251. The other end of the guide rod 27 extends into the guide groove 251 and can move in the guide groove 251 along the track of the guide groove 251. A film removal head 29 is provided on the side of the connection block 28 away from the connection seat 26. In this embodiment, a suction cup is provided at the end of the film removal head 29, and a negative pressure structure is connected in the suction cup to suck or put down the electrode plate 8. In order to convert the linear motion into the motion when the suction cup takes the film, the pull rod 22 and the moving block 24 are connected to the guide rail 23 through a connecting shaft 20, so that the pull rod 22 and the moving block 24 can rotate around the connecting shaft 20, and the connecting seat 26 and the moving block 24 are rigidly connected, and the guide rod 27 is rigidly connected to the connecting seat 26 and the connecting block 28. The guide groove 251 is generally parallel to the guide rail 23, but the distances from both ends to the guide rail 23 are not equal. When the moving block 24 drives one end of the connecting seat 26 to move linearly, the cooperation between the guide groove 251 and the guide rod 27 drives the film taking head 29 to move back and forth between the end of the feeding channel 11 and the conveying chain 41 of the stacking mechanism 4.

[0042] like Figure 9-12As shown, the lamination mechanism 4 includes a conveyor chain 41, a conveyor plate 42 and a partition 43. The conveyor chain 41 is located at the end of each loading channel 11, and conveyor plates 42 are provided on both sides of the conveyor chain 41. The two sides of the positive plate 82 are respectively placed on the conveyor plates 42 on both sides of the conveyor plate 42 for transportation, and a partition 43 is provided vertically above the conveyor plate 42, but the partition 43 only extends from the output end of the conveyor chain 43 to the lamination mechanism 3, and the two sides of the negative plate 81 are respectively placed on the partition 43 for transportation. The conveyor chain 41 is also provided with a plurality of upwardly protruding push blocks 411, and the top ends of the push blocks 411 exceed the partition 43, and the positive plate 82 on the conveyor plate 42 and the negative plate 81 on the partition 43 are pushed forward synchronously by the push blocks 411, so that the positive plate 82 and the negative plate 81 at the end of the conveyor chain 41 can be paired.

[0043] Moreover, if Fig.12 As shown, the separator 43 is warped upward near the end of the sheet wrapping mechanism 5, so that the positive electrode plate 82 wrapped with the plate paper can more smoothly enter the space between the conveying plate 42 and the separator 43. When laminating, the positive electrode plate 82 wrapped with the separator paper is placed on the conveying plate 42 at the starting end of the laminating mechanism 4, and the negative electrode plate 81 is placed on the separator 43 at the other end of the laminating mechanism 4. When the push block 411 pushes the positive electrode plate 82 to the bottom of the negative electrode plate 81, the positive electrode plate 82 and the negative electrode plate 81 are pushed forward together to complete the laminating operation.
